The patellar ligament (anterior ligament) is the central portion of the common tendon of the Quadriceps femoris, which is continued from the patella to the tuberosity of the tibia. Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. Introduction ( Joints or Articulations Sutural ligament Fibrocartilages The patella or kneecap is a thick triangular Bone which articulates with the Femur and covers and protects the knee joint Narrow below where the anterior surfaces of the condyles of the Tibia end in a large oblong elevation the tuberosity of the tibia, which gives attachment to the Ligamentum Medical Subject Headings ( MeSH) is a huge Controlled vocabulary (or metadata system for the purpose of indexing journal articles and books Elsevier, the world's largest Publisher of Medical and Scientific literature, forms part of the Reed Elsevier group "Quads" redirects here For other uses see Quad The quadriceps femoris ( Latin for "four-headed of the femur" also The patella or kneecap is a thick triangular Bone which articulates with the Femur and covers and protects the knee joint The tibia, shinbone, or shankbone is the larger and stronger of the two Bones in the Leg below the Knee in vertebrates and connects
It is a strong, flat, ligamentous band, about 8 cm. in length, attached, above, to the apex and adjoining margins of the patella and the rough depression on its posterior surface; below, to the tuberosity of the tibia; its superficial fibers are continuous over the front of the patella with those of the tendon of the Quadriceps femoris.
The medial and lateral portions of the tendon of the Quadriceps pass down on either side of the patella, to be inserted into the upper extremity of the tibia on either side of the tuberosity; these portions merge into the capsule, as stated above, forming the medial and lateral patellar retinacula.
The posterior surface of the ligamentum patellæ is separated from the synovial membrane of the joint by a large infrapatellar pad of fat, and from the tibia by a bursa. Synovial membrane (or synovium) is the soft tissue that lines the non- cartilaginous surfaces within Joints with cavities ( Synovial joints
It is also sometimes called the "patellar tendon". A tendon (or sinew) is a tough band of Fibrous connective tissue that usually connects Muscle to Bone and is capable of withstanding tension [1]
